class TextEncoder

An implementation of the WHATWG Encoding Standard TextEncoder API. All instances of TextEncoder only support UTF-8 encoding.

const encoder = new TextEncoder();
const uint8array = encoder.encode('this is some data');

The TextEncoder class is also available on the global object.

Properties

readonly
encoding: string

The encoding supported by the TextEncoder instance. Always set to 'utf-8'.

Methods

encode(input?: string): Uint8Array

UTF-8 encodes the input string and returns a Uint8Array containing the encoded bytes.

encodeInto(
src: string,
dest: Uint8Array,
): EncodeIntoResult

UTF-8 encodes the src string to the dest Uint8Array and returns an object containing the read Unicode code units and written UTF-8 bytes.

const encoder = new TextEncoder();
const src = 'this is some data';
const dest = new Uint8Array(10);
const { read, written } = encoder.encodeInto(src, dest);
